Fibre Optics Technology over the past century has advanced greatly. Fibre optics however is being utilized since more than a hundred years. Optical fibre is a model that has evolved greatly over time. From guided transmission lights experiments to lasers and light emitting diodes (LED)‚ and to dense wavelength-division multiplexing (DWDM)‚ the area under which optical fibre can be used has expanded. One of the modern and commonly used applications

the information to the remote location receiver by using RF transmitter then the receiver will receive the details of agricultural field and will control. There are three receiver sections‚ in this first the soil sensor will see the fertility of the field and it is given to the pumping motor in the receiver section by using microcontroller. The second one is temperature sensor and it is given to the DC fan attached to the microcontroller in the receiver section and the third one is humidity

Wireless Controller Robotic Arm using Arduino Uno Abstract—This paper presents an innovative wireless robot arm gripper that replicates human arm motion. The development of this robot is based on the Arduino Uno that will interface with the wireless PS2 controller to the robotic part that replicated by the servo motors. The servo will moves the robotic arm‚ base and the gripper through 180° from the default position which is 90°. The S06NF STD servo motor has been placed at the arm part. It

HAND GLOVE MOUSE here we designed and built a wireless computer pointing device with accelerometer based movement control. Our implementation allows the user to wear a set of hardware (a glove and connected armband) and control a cursor through different hand orientations and finger presses. Users can operate their computers with their hands in midair without the hassle of desks surfaces or wires. The motivation for this project was to create an intuitive glove-based pointing device for multiple

1. INTRODUCTION 1.1WIRELESS ELECTRONIC NOTICE BOARD USING R.F:- Data Security is primary concern for every communication system. There are many ways to provide security data that is being communicated. However‚ what if the security is assured irrespective of the hackers are from the noise. This Project describes a design of effective security for data communication by designing standard algorithm for encryption and decryption. R.F. is a PAN technology based on the IEEE 802.15.4 standard.

It sends signals to the immediate device which confirms the accident and sends emergency note. The transfer of signals should happen within milliseconds of collision. • GPS Sensor GPS stands for Global Positioning System. GPS Sensor serves like a receiver provided with an antenna.

refers to a class of radio navigation systems based on the difference in timing between the reception of two signals‚ without reference to a common clock. This timing reveals the difference in distance from the receiver to the two stations. Plotting all of the potential locations of the receiver for the measured delay produces a series of hyperbolic lines on a chart. Taking two such measurements and looking for the intersections of the hyperbolic lines reveals the receiver’s location to be in one of
